To all whom it may concern:

Be it known that I, AUBREY A. Aocoon, a citizen of the United States,residing at Kansas City, in the county of Jackson and State of Missouri,have invented certain new and useful Improvements in Oil Burners; and Ido declare the following-to be a full, clear, and exact description. ofthe invention, such as will enable others skilled vin the art to whichit appertains to make and use the same, reference being had to the.accompanying drawings, and to the figures 0 reference marked thereon,which form a part of this specification.

This invention relates to an oil burning system including a feed tankand a burn r for vaporizing hydrocarbon oils, prepara tory to theircombustion for the production of heat. The invention contemplates anovel form of hydrocarbon burner including a mixing chamber and anhydraulic pressure feed tank which may be. attached to the service mainof a city water system to cause the oil to be put under pressure so.that it will feed to the vaporizing chamber. The generic embodiment ofthe invention also comprises certain novel details of construction whichare included in the preferred em hodiment of the inventionhereinafterspecifically described and illustrated in the accompanying drawings, inwhich:

Fig. 1, is a perspective view of hydrocan bon oil burning system, partof the pressure tank wall being broken away to illustrate the interiorthereof. 7

Fig. 2, is a vertical, longitudinal, sectional view through the burnerand the mixing chamber, part of the vaporizing chamber being shown inthe section.

Referring now tothe drawings by nu morals of reference 1 designates atank, illustrated as a vertical, cylindrical tank closed at itsrespective ends. At the lower end of the tank is a valved water inletpipe 2 and a drain pipe 3. At the top of the tank is a valvedoil inletpipe 4-. by means of which the hydrocarbon oil can be introduced intothe tank from the top. 5 designates an air vent; extending from a pointadjacentto the bottom of the tank 1, and projecting through the top is apipe 6, controlled by a valve 6. The pipe 6. communicates with a pipe7.. which extends through the top of the tank a short distance asindicated at 8 and is c011 trolled by a valve 9 between the pipe 6 and,to the coupling 11.

the tank 1. The pipe 7 communicates with a vaporizing tube 10 and isconnected to the vaporizing tube by a coupling 11, in which valve 12;The vaporizing tube is in the form of a split tubular ring, the splitends terminating in two tubular legs or extensions 13 and l t, the leg13 being connected Leg 14': has a depending extension 15, carrying anozzle 16, adapted to be controlled by the valve'17.

The nozzle is spaced from, but in axial alignmentwith a mixing chamberconiprising a tubular body 1 8,"considerably larger than the nozzle. andinto which thenozzle discharges the hydrocarbon oil in the form of vaporgas. The mixing chamber 18 projects through a double wall burner conehaving two perforate walls 19 and 20. The perforations 21, atv the basevof the conical wall 20 admit the fuel mixture into the space 22, wherethe mixture may be .admitted through the perforations 23. It will beobserved that the perforations 21 are.

relatively large and are in circular series near the base of the wall20, wlnlethe perforations 23 extend entirely throughout the wall 19 sothat the burning flame will be coextensive with the cone. The conesupports a burner plate or disk 24, having a conical recess 25, intowhich the apex of the cone is received and near the perimeter of theplate 24: are J-bolts 26, the curved ends of which engage the split ringshaped vapor- The priming tube or burner 29 may be associated with theburner to preliminarily heat the cone. Such burner may be connected tothe gas supply pipe and may have an arcuate end 30, following the curveof the burner cone as shown in Figure 1.

Assuming that the parts "are properly assembled and that the oil hasbeen introduced into the tank 1, the valve 81 in pipe 2, may be crackedso that water will flow into the tank, and since the specific gravity ofoil is less than that of water, it is obvious that the oil will float onthe column of water admitted to the tank.- Since the water in allservice pipes is under pressure, it will be ios apparent that the oilwill be put under pressure so that if the Valve 9 is; cracked and thevalve 12unseated, oil Willflow into the vaporizing tube or chamber 10,and that if this tube has already been heated by a primer such as theburner 29, the oil will be vaporized or gasiiied; then if the valve 17is open the vaporlzed oil W111 enter themixing .eha mber'l8 to combinewith the air toprovide a combustible fuel mixture which is introducedinto the conical chamber 32-:Erom which it will pass throughthe openings21 into the space between the \va-lls l) and 20 of the cone and beemitted through the perforations 23,'W l1018 it may be consumed. Having'in mind that the pressure in the tank 1 \villbe equal in all directions,it is obvious that if the valve6 in pipe 6 is unseated While the valve 9is crachech Water will be admitted into the pipe 7,' so that Waterandhydrocarbon oil can be fed to the vaporizing chamber, the hydrocarbonoilbeing converted into oilvapors and the Water into Water tank will beentirely full of Water and have no oil in it. Then the valve 31 may beclosechthevalved plpe 8 opened and Water drained from'the tank, anew'charge of oil may then be introduced into the tank through valvedpipe 4.
